From one point of view that is one reason when I looked used I have never considered refurb. Yes they come with a warranty but never an clear identification about total mileage, I often found that odd. Unlike used cars where milage is always shown and priced into the final sales price.

OTAH for a camera that can do 200K what is 5% usage..

Thus I've always considered both and gone the used route, CL local or FM and so far, knock on wood hd good look.

My other thought 10K is a lot for some casual or pro to shot then return, sound like border unethical return, fully within Nikon's though to sell as "refurb"
